Git-ssh登录github

1. 生成你的ssh-key
1. $ ssh-keygen -t rsa -b 4096 -C  "SaphhireCastle@163.com"
2. 默认目录为：/Users/you/id_rsa_email 多key好区分
3. 输入passphrase，统一123456
2. 将key加入agents中
1. $ ssh-add ~/.ssh/id_rsa_SapphireCastle
2. 查看现有key: $ ssh-add -l
3. 删除key: $ssh-add -D
4. 查询ssh-agents版本：ssh-add -v
5. 打开/关闭ssh：$ sudo systemsetup  -setremotelogin on/off
3. github服务器加入公匙
1. 复制本地公匙 $ cat  ~/.ssh/id_rsa_SapphireCastle.pub
2. GITHUB -> Settings -> SSH and GPG keys -> New SSH key
4. 验证是否连通
1. $ ssh -T git@github.com   此处为config中配置的host
